I was not able to find the the data sheet for the LED Display C8021-11. Does anyone know of where I may be able to find the data sheet for it.I am working on a LED Counter, Multiplexing home project. Thank you in advance

Thank you very much for the time taken to provide the given information. I did try to figured out the pin connections but there were some pins that I was not able to determine what their functionality is for. I used my power supply and the appropriate current limiting resistors to light the LED s but the out come was not a success. Thank you
